Im a brickie with not much mechanical experience but it was the mk4 Astra gsi that attracted me to your channel. Keep uploading im still learning about the propper way to mod and safely too. Its not often you come across a fountain of wisdom.... that i can understand at the same time.👍
I got a Zafira GSI a while ago as a second car, I'm going to be doing this at the weekend with new cam cover, seal, oil cap and seal and replacing the oil drain pipe with the revised item as well as I'm wanting it the way it should be. I'm like yourself in that things should be done properly with torque settings, etc. I love your videos, you explain things so well and your knowledge is brilliant. Keep up the great work 👌🏼
Hi Aaron, I´ve replaced and installed my gasket properly about a month ago, but it quite leaks all over again. It got my attention when I came around seeing the rocker covers offered for sale new on the Courtaney site that they themselves go after a certain age-mileage?? Is that a common thing as you mention it here in your vid? Cheers
Hi there, yes it’s extremely common! The most common leak. They warp. On ebay you can buy them new for £100

Hello! This video is the best off all out there! I have try to replace Gasket 3 times now. 2 by my self and 1 time i let the mechanic do it. The last time i buy a brand new Cover. I did rebuild my car recently and found out leaking oil from my cover again!! Its come out from right side on top of the head. just after those blobs. So irritating So now i am study if i can find out why. you seams to now exactly how to do this on this engines so wonder if there are any chans to contact you by e-mail or chatt?
Another top vid but was amused at end of vid when you said about oil leaks mine leaks from the head thought it was stems so changed them with a cambelt and water pump kit to no avail lol it don't smoke any more or burn oil but can still see it streaming out ffs😔👍👍
gaz 1982 mines the same streaming out from somewhere but can’t find the leak! Doing the clutch soon so I’ll be removing the flywheel and doing the rear main seal at the same time.
I think I might replace my rocker cover next see it that helps it is a bit old and scabby looking anyway so it’s most likely been on there since 2002 lol
@@AaronUnknownPerformance thank you mate. I currently use 5w40 in my Zafira GSi which is running just under 300bhp (I love the thing!). Would you advise I go to 10w40 fully synthetic or even 10w50 fully synthetic - I know the engines get very hot under load...thoughts would be greatly appreciated!!
Mines other side can see it coming out of no1 exhaust port from behind manifold but don't no if it's coming from exhaust port or a bodged broken stud extraction but it's my only vehicle so can't afford to have it off the road lol
@@AaronUnknownPerformance That's my thought bud I've only topped up once in 4k where before stems was every 200 mile lol going to change head after Xmas as it's not causing any running issues just now just smells of oil
Ok how have you got your breather tank plumbed in ? I can see we’re the too back pipes go but is the larger pipe coming to the front just vent to atmosphere?? Thanks for reply
Aaron can you suggest the best way to get the front pipe to seal with the v-band clamp I just can’t get mines to sit correctly at all while tightening the clamp I even bought the gasket for it still no luck, it’s leaking a lot and causing boost issues

Awesome!
The Astra messiah!! Thanks Aaron learn a lot from your videos!
Thank you for this good instructions. Greats from Germany.

Love the video bud. Did exactly as u said. Can't check for those total leaks tho due to me not cleaning the engine prior to gasket change
This was really useful fella, quality content 👍🏻
THANKYOU SO MUCH -FROM AUSTRALIA

Yeah its often mistaken for other issues when it leaks from the cover

Gaskets on my to do list for winter, if the coil pack rubber boots are split are they replaceable or is it just a new coil pack?
Nice one Chris! Nope you can buy repair kits complete with new springs
Will the old aluminium cover fit the z20leh motor?
hi top videos mate were can I find the torque settings for theys engines and car?
Hi, mate great videos any chance you know the bolt lengths for the courtenay top hat?
I'm really struggling to get the valvecover off My Astra g x16xel as im about to change the gasket
Amazing video mate! A man with a wealth of knowledge in these cars.
Out of curiosity - what engine oil do you run in your LETs/LEHs??
Thanks
Thankyou mate! I mostly use 10/40

Hi mate, where did you manage to find a mini torque wrench? Trying to find one to order 👍
Good work
What is the torque spec for cam cover from aluminium? Also 8 Nm? I have the older 16 valve x22xe
Got any tips on changing a manifold gasket, looks like I got oil behind it? Changed oil cap seal, and cant see any oil leaking from cam cover?
Good vids man , hello from México
Welcome Jinx thankyou 💪🏻
Can you make a video about x20xev inlet camshaft replacemant instead z20let camshaft?

It will be from the stud hole mate normally people drill them out too far

Hey man im currently in Germany. Are there anysites or places where you reliably get parts for these engines?
Ok how have you got your breather tank plumbed in ? I can see we’re the too back pipes go but is the larger pipe coming to the front just vent to atmosphere?? Thanks for reply
Hi mate. That pipe drops down to the oil catch can to stop vapour smells
Shit, I used three bond on the right side of the rocker cover but not the timing belt side, is it 100% it's gonna leak? all torqued up to 9nm.
Aaron can you suggest the best way to get the front pipe to seal with the v-band clamp I just can’t get mines to sit correctly at all while tightening the clamp I even bought the gasket for it still no luck, it’s leaking a lot and causing boost issues
Is your pre cat separate or a complete downpipe?
Aaron Unknown separate mate
Mikey B always fit the precat separately connect the down pipe but leave it loose until the end
Thanks Aaron will give that a try. Thank you for your help again bud. Much appreciated 👍🏻😀
Unknown,any ideas as to why I got sludge in intercooler pipes
Oil breather vapours from intake being condensed by intercooler
Aaron Unknown ok so catch can would solve this? Thanks
Hi mate can I ask how you have your catch can plumbed in ?
its a breather tank mate
Looks like u can fix my car Aaron
